House Wren

Troglodytes aedon

A common hyperactive midget found throughout the state. A
very aggressive courtship and nesting ritual involves the male building numerous
"dummy" nests in any available cavity (nest boxes, trees, buildings,
fences, etc). The female selects one of these, and the male completes that
nest. House Wrens will also aggressively chase other species from
potential nesting sites, even going so far to destroy their eggs and kill their
young.
